- T all whom it mag concern:

' I Be it known that I, Kms'rornn ANn'EnsoN,

a citizen of the United States, residing at Larson, in the county of Burke and State of North Dakota,;hav e invented certain new and useful Improvements in Harrow Attachments for Plows, of which the followin isa'specification. T

inharrow attachments for plows. 'Ihe chief object of the invention is to 'provide an attachment of-this type by means of which the harrow may-be lifted clear of the ground to cleansethe knives or teeth should they become clogged. A further object is to provide means for retaining the harrow in raised position when desired. A further object 1s to provide manually operable means whereby the front end of the bar-- row may be adjusted relatively to the plow. A further object is toprovide a device of this type that it simple in construction, efficient in operation and cheap to manufacture. With the foregoing and other objects in view the invention consists in the-combination and arrangement of parts to be hereinafter fully described, pointed out in the appended claims and illustrated in the accompanying drawings which'form a fication and in which Figure 1 is a view of my improved harrow attachment in side elevation illustrating its application, the dotted lines showing the harrow in raised position.

Fig. 2 is a top plan view of the device as applied to a plow.

Like reference characters I denote corresponding parts in both views.

The reference numeral 1 denotes a sulky' plow to the frame 2 of which I secure, by bolts 3*, the rearwardly extending down- .wardly curved bars 3, 4 in the ends of which the rotary transverse shaft; 5 is journaled,

adapted for engagement with the pron'ged end of the dog 9 that is secured by pivot 10 to the bar 4, said dog serving to release ably retain the lug 7 in raised position when desired; To the shaft 5 I secure one end of the reach bar 11' which is secured at'its other end to the bar 12 which is made fast to the harrow frame 13. A pedestal 14 secured to the harrow frame 18 beneath the reach'bar his 11117611131011 relates to improvements part of this speoi V r Specification of Letters Patent. Patented 11 9 1920.

11 and in advance of the bar12 is-adapted for engagement with the, reach bar as the forward endofthe'harrow frame is raised in; a 'manner to be hereinafter described.

To the very front end 15 of the harrow 'frame'I secure a link '16 to which one end of a chain 17 is secured, the opposite end of said chain. being secured to an adjusting screw 18 arranged in a bracket-19 formed integral with oneend of thereach bar ,11,

said'screw being provided with the nut 20.

By-rotation of the adjustingscrew in one direction the chain 17 may be drawn taut and the front. end of the harrow frame raised. Rotation of the screw in the oppos1te direction will obviously slack the chain 17 and lower the harrow end. Pressure upon the free end of the foot lever 6 will partially rotate the shaft 5 and cause the reach bar to raise the harrow frame partially or entirely oil the ground as-shown in dotted lines in Fig 1. As the reach baris secured nearer the front end than the rear .end of the harrow frame the front end of the frame will be raised first until the ped'es tal 14 engages with v the reach bar and at that time the harrow frame will be raised as a unit. When the shaft 5 has been turned to a certain point the dog 9 can be placed in engagement with the notched portion 8 of the lug'7 to retain the shaft and harrow 1. In a harrow attachment for plows, a

rotary shaft operatively carried by the plow,

a foot lever made fast to one end of said 7 rotary shaft, a reach bar connecting the opposite'end of said rotary shaft and the harrow frame, and a pedestal carried by the harrow frame beneath the reach bar, and disposed in advance of the point of engagementof said reach bar with the harrow frame.

2. In a harrow attachment for plows, a

; rotary shaft operatively carried by the plow,

afoot lever made fast to one end of said rotary shaft, a reachbar connecting the opposite end of said rotary shaft and the har row frame, a pedestal carried by the harrow'frame beneath the reachbar and disposed in advance of the point of engagement of said reach bar with the harrow frame,

and means carried by the plow andsaid rotary shaft for releasably locking them to V gether in a predetermined position.
